Require a BitLocker pre-boot PIN

TPM-only BitLocker is tidy until you remember what is left exposed when the machine can unlock itself. BitLocker PINs are the small, awkward step that makes a stolen laptop less cooperative, and I trust that far more than wishful thinking about physical security.

Secure connectivity principles in water sector OT

Secure connectivity principles only work when the boundary is real, not decorative. I’ve seen too many remote paths that looked neat on paper and fell...

Monitoring radio, transport and core faults

Private 5G resilience does not come from a cheerful dashboard or a nice radio map. I want to see where the attach failed, which path dropped, and...

Pre-boot authentication for BitLocker

TPM-only BitLocker is convenient, but convenience is not the same as a proper boundary. BitLocker PINs push that line back to pre-boot, which is where...

Data exfiltration signs from signed Setup.exe flows

Signed `Setup.exe` did not fool me for long, because the runtime behaviour was wrong from the start. The interesting bit in cloud environment exfiltration is usually the small `.config` file beside it...

Hardening ig build against command injection

Inspektor Gadget OCI images sound harmless until a build value slips into shell syntax and the pipeline starts executing it for you. I prefer build steps that stay boring, because once they stop being...

Prototype pollution in Adobe Acrobat PDF code paths

Prototype pollution in Adobe Acrobat PDF code paths is not a neat edge case, it is what happens when privileged JavaScript trusts the wrong shape of data. I keep coming back to the same point,...

Human-in-the-loop AI pentesting for exploit paths

AI pentesting is useful when it speeds up the grunt work and leaves judgement where it belongs. I care less about noisy findings than about whether a small mistake can be chained into a working path,...

Formal verification boundaries in corecrypto

corecrypto formal verification is useful right up to the point where the code stops being plain C. I trust the proof more than the marketing, but only if the compiler output still looks like the model...

pipe_buffer tmp_page reuse in Linux kernel

tmp_page reuse sounds neat until you try to make it behave, and then the pipe accounting starts getting in the way. I have found the useful part is usually not the obvious corruption, but the ugly...

GitHub exposure of AWS GovCloud credentials

Public repos are brilliant at preserving bad decisions, and AWS GovCloud credentials are exactly the sort of thing that should never survive a commit. Once they are out, the clean-up is only half the...

Hardening consumer routers against botnet abuse

Consumer routers are still being dragged into IoT botnets because the easy mistakes never went away, default logins, exposed admin pages, and forgotten services. I would rather spend ten minutes...

Rotating AWS GovCloud secrets after repo disclosure

AWS GovCloud credential leakage is not a tidy mistake, it is a time problem. Once a secret hits public GitHub, I treat revocation, search, and handoff as one job, because leaving even one copy alive...
